The bookmobile, tested: no mobile service ever ran to this ground — the county's wheels were South Bend's

Before 2004 · MPHPL side tested negative; SJCPL's bookmobile course at boundary size

The test on this ground's own system: Whether the Mishawaka-Penn-Harris Public Library ever ran a book wagon or bookmobile to Harris or Clay township before the Harris Branch opened in 2004 — the only library service the farm townships could have had, in the decades when they had no library at all — was tested against MPHPL's annual reports, its Long-Range Plan, and its branch record as the open sources carry them. No bookmobile appears in any of them. The negative is structural, not just archival: Harris Township had no library service of any kind until the district expanded into it in 2001, and the branch that followed in 2004 was a building, not a route — there was no district service to put on wheels before it. MPHPL's mobile service on this ground closes as a tested negative.

The county's mobile service, at boundary size: The county did have a bookmobile, and it was the other system's. The St. Joseph County Public Library ran its first Bookmobile in 1953, and its own history states the purpose in the phrase the checklist's pattern needs: it "served residents who were not served by a branch." The Readmobile — SJCPL's third bookmobile — debuted in 1996 and was decommissioned in the 2000s, a course carried in the Indiana Memory / Michiana Memory brochure record of about 2007. Both are South Bend's system and South Bend's wheels, boundary-printed here. Whether SJCPL's bookmobile ever stopped in the CDP's Clay Township portion — the one part of this ground that sits outside MPHPL's district, and whose library standing is itself unsettled as GAP-GOV-5 — was not settled by any source reached, and it is named here as an open question rather than claimed either way: the SJCPL bookmobile's route sheets, if they survive, are its settler.
